Speaker-room interaction is typically the most important performance-limiting factor of any high-end audio system. Every listening space introduces errors that can be in the magnitude of dozen decibels or even more. These errors are most pronounced at the bass and lower midrange regions, where the classic acoustic treatment loses its effectiveness.
DSPeaker designs and manafucturers a room of subwoofer and room EQ solutions which correct for the negative effects of the listening space. The results really have to be heard to be believed.
